Brain Region Volume and Criminality?

Studies by Adrian Raine, University of Pennsylvania, suggest a connection between reduced amygdala function at age three and possible later criminal activity. As an aside:

Adult psychopaths appear to have an 18% reduction of the volume of the amygdala compared with non-psychopaths.

The orbital frontal cortex tends to be associated with being antisocial when its volume is smaller; as a group, men have a smaller orbital frontal cortex than women, which may help explain why men as a whole tend to commit more crimes than women.
